When Phil Collins took the helm, the band really became accessable and more user friendly. Purists might say that's when the band sold out, but I think they put out some really great stuff. I even like stuff off their Invisible Touch album (college era for me...) Good memories to those songs.
You're right, Peter Gabriel is insufferably pretentions and self-righteous.
Pretentious, affected, narcissistic and contrived are the salient, operative words of our times as far as I'm concerned. Oh, and phony!
I agree with the Buggles that "Video killed the radio stars". It's become a medium of posing, dancing and outfits and haircuts.
